So they figured this out in 15 seconds which is the time it took to make the decision? Why not take the entire 45 seconds to double check?
If the FARC took 45 seconds to come up with their decision that would mean the footage is inconclusive and goal umps call which was I think it’s a goal
AFL can’t have that after 10 seconds they came up with BS ball clearly over the post :bash

The triangulation referred to is something like below. Basically, if two camera angles show the ball over the post at the same time, then the ball was over the post.


Not quite the “definitive footage” some in the media were hinting existed but still valid. The problem is why are we only hearing about this now? If this was how the decision was made in the ARC, why not say so at the time? Or at least in the days following?
This was on twitter and reddit in the hour or so after it happened. If you run an experiment yourself it has to be true. The only way the ball can be over the post on two different angles where the shot is taken simultaneously is if it is over the post (or 180 degrees it may not be over).

But……..

With that said there were also plenty of people saying that the two shots on different angles with the balls over the post were at different times (which would prove it wasn’t over the post). It also needs to be exactly over the post and not half over, half off, which can be parallax. The images are just pathetic and don’t make this clear either. Surprised it wasn’t claimed as a UFO going over the post by the antivax movement.

Again if the AFL had this, and part of the arc processes had already worked this type of scenario out (which they should have) then they clearly could come out with it and communicated it immediately.

I saw this on Reddit when it was posted. How can they tell 100% that I he ball is over the post without aerial shots?

A 2d plane is no good for making error free calls. What's even worse is the quality of our field shots from the cameras. The ball looks like an interpolated blurry mess at the best of times, let alone in the poorly lit stratosphere of the top of the goalposts.

Don't fall for the spin. It is garbage.

Is that the best they can come up in 2 weeks? Complete nonsense and as others have pointed out, 100% gaslighting.

So this "triangulation" process took 15 seconds and was definitive enough to overrule the goal ump who was in perfect position?

1663633756176.png

Let A(x1, y1) and B(x2, y2) be the two observation points with bearings towards the landmark as α and β, respectively. If C(x3, y3) is the location of the landmark, the points A, B, and C form the vertices of a triangle, where:

∠CAB = θ1
and
∠CBE = θ2.

Using coordinate geometry, we can write the formula for the slope of line AC as:

tan(θ1) = (y3 - y1) / (x3 - x1) .... (1)

Similarly, for the line BC we can write:

tan(θ2) = (y3 - y2) / (x3 - x2) .... (2)

Solving equations (1) and (2) for x3 and y3, we get:

x3 = [(y1 - y2) + x2 * tan(θ2) - x1 * tan(θ1)] / [tan(θ2) - tan(θ1)]

and

y3 = [{y1 * tan(θ2) - y2 * tan(θ1)} + (x2 - x1) * tan(θ2) * tan(θ1)] / [tan(θ2) - tan(θ1)]


Wow...these ARC guys are bloody good (and fast) at trigonometry!

Did you hear about the constipated mathematician?
He worked it out with a pencil.

Hang on - they don’t have to do all the arithmetic themselves - they have a slide rule

It's theafl method of (S)triangulating any further discussionon the matter, no further correspondence will be entered into. Any further attempts by the RFC will result in $20,000 fine to Marlion Pickett.

I have avoided AFL360 for several years due to the hosts, just unbearable to watch. I do see the clips of Jack when he is on, that's about it.
On another matter relating to Fox shows, does anyone know if The Bounce has been cancelled?

You have to take note of what it actually says: "If the ball is in line with the post simultaneously from two angles, the only place it can be is directly over the post". Yep, that's true.

So what?

The question remains - was the ball in line with the post from 2 angles simultaneously? Just stating a geometric fact tells us nothing, plus I would not trust them to show footage which has not been adjusted to alter the timing so it looks like this. We have all seen the footage from the fan behind Lynch and let's face it: the ball was not simultaneously in line with the post from 2 angles so the above is completely irrelevant and a clear distraction.

Agree... Jason Dunstall is wasted by Fox hosting that rubbish when he should takeover AFL360!
Yes for sure TBV. Chief and Nick Roo would be a great combo, with Kath Loughnan also good at hosting various shows.

I was at the game, when the footage came up, and people realised the call was a goal, tiger fans fist pumped and hugged and high fived, brisbane fans bowed their heads. The whole crowd accepted in that instant that the goal couldn't be overturned based on that footage and we had won.

To me, to say 'clearly from this footage we can see the ball is over the post' , is exactly the same as looking at those famous old 1950s blurry photos of a saucepan lid hanging by a string and saying 'clearly we can see a UFO'.

It all makes sense now. Why didn’t they just say that from the beginning and we would have been saved a lot of confusion. Did they think we were idiots and wouldn’t be able to understand all that?
